Your upshot is similar in nature to:

• Brackets in get-go column in table give "Missing number, treated equally zero" mistake




• Fault with square bracket in tabular array

...even though in this case you're using eqnarray. You'll take to avoid \ grabbing the subsequent [ on the next line and thinking it's expecting an optional argument. Employ \relax or {}[a,b):

                  documentclass{article}
                       usepackage{amsmath}
                    
                       brainstorm{document}
                    
                       brainstorm{align*}
                      (a, b) &= { x in X mid a < x < b }       \
                      (a, b] &= { x in Ten mid a < ten leq b }    \relax
                      [a, b) &= { x in 10 mid a leq x < b}     \relax
                      [a, b] &= { ten in 10 mid a leq x leq b }.
                      end{marshal*}

You could likewise use the interval bundle to specify intervals, which removes the verbatim use of [ around line-breaks \, but instead sets the interval using a macro:

                  documentclass{commodity}
                       usepackage{amsmath,interval}
                    
                       intervalconfig{
                      soft open fences % Uses ( and ) for open intervals, rather than ] and [
                      }
                    
                       begin{document}
                    
                       begin{align*}
                      interval[open left, open right]{a}{b} &= { ten in X mid a < x < b }        \
                      interval[open left]{a}{b} &= { x in X mid a < x leq b }     \
                      interval[open right]{a}{b} &= { x in 10 mid a leq x < b}      \
                      interval{a}{b} &= { ten in X mid a leq x leq b }.
                      end{align*}
                    
                       terminate{certificate}
                                  

Your upshot is similar in nature to:

• Brackets in first cavalcade in table requite "Missing number, treated as zero" mistake




• Error with square bracket in table

...even though in this instance you're using eqnarray. You'll have to avert \ grabbing the subsequent [ on the next line and thinking it's expecting an optional argument. Use \relax or {}[a,b):

                  documentclass{commodity}
                       usepackage{amsmath}
                    
                       begin{document}
                    
                       begin{align*}
                      (a, b) &= { x in X mid a < x < b }       \
                      (a, b] &= { x in X mid a < x leq b }    \relax
                      [a, b) &= { x in X mid a leq ten < b}     \relax
                      [a, b] &= { 10 in 10 mid a leq x leq b }.
                      end{align*}

You could also apply the interval package to specify intervals, which removes the verbatim use of [ effectually line-breaks \, but instead sets the interval using a macro:

                       usepackage{amsmath,interval}
                    
                       intervalconfig{
                      soft open fences % Uses ( and ) for open up intervals, rather than ] and [
                      }
                    
                       begin{certificate}
                    
                       begin{align*}
                      interval[open left, open right]{a}{b} &= { x in X mid a < x < b }        \
                      interval[open left]{a}{b} &= { x in X mid a < 10 leq b }     \
                      interval[open correct]{a}{b} &= { x in 10 mid a leq ten < b}      \
                      interval{a}{b} &= { x in Ten mid a leq 10 leq b }.
                      terminate{align*}
                    
                       end{document}
                                  

Your issue is similar in nature to:

• Brackets in first column in table give "Missing number, treated as nil" fault




• Mistake with square bracket in tabular array

...even though in this case you're using eqnarray. You'll have to avoid \ grabbing the subsequent [ on the adjacent line and thinking information technology'southward expecting an optional statement. Apply \relax or {}[a,b):
